To The Skyline R33 Gtr Guys: Is 245/45 Wobbely?

[Torques]

I got myself a pair of R33 GTR wheels for my GTST with 245/45/17 on them.

They're snow/winter tyres since they came from Japan.

I like the size since the tyre diameter is 2cm more than the standard 205/55/16

It looks good I find and gives good riding comfort.

(have a lot of potholes and speed bumps here)

In your experience is 245/45 a good choice for your cars or gives 255/40 more control?

Size won't cause wobbley-ness, probably something wrong with balance or the tyre itself. I like the run the widest tyres possible, but since you have a GTS-t, I'd look at the guard to tyre clearance. Slightly taller sidewall would help with ride, so I'd stick with 245.

Difference between 245 and 255 isn't much, the tyre design/construction/compound would make a bigger difference.

Um. Wat?

20mm extra diameter is not a good thing. Hello speedo error. Hello taller gearing.

For all that.....there's nothing wrong with 245/45 as a tyre size in itself. It is neither going to be much better or much worse than a 255/40 in any real way. You'd be hard pressed to feel the difference in grip, firmness, sidewall flex, traction....anything. The 255 would be the better choice just for being closer to the right size (rolling diameter), that's all.

If you leave them on there 'til they wear out, and you want to go for wider tyres that still retain some of the extra sidewall height, you could probably squeeze a 265/40 onto 9" rims on that car. Gains you a bit extra rubber on the road and half the extra sidewall you have now.

Alright,

Thanks .. I was just thinking since 255 and 40 profile has smaller side-walls it would make a a real world difference

(just by using the link I provided in my first post)

I have the 245 on right now and clearance wise it seems ok

Hi!

Speedo error seems no too bad.

(that's compared to the standard GTSTs)

Look here:

And 3% longer gearing seems to be an option,

Here's how it looks at the moment:

I run 265's on the back on 9" rim. I'd like to give a comparison to other size tyres but the last time i ran different size tyres they were 32 GTR tires, about 225 wide and rather old. Also car was stock and I ditched them about 4 months after buying the car

If you want to wait till you wear the current tyres out, fair enough. But go the 265's if you wont run into any problems with rubbing. I think mine are 265/35's but cant say 100% and too lazt to walk 4m to the car

[Torques]

Thanks,

265 sounds wide is that also on the fronts?

With 245 at the front and 30 offset the tyre seems already at a narrow clearance towards the arches.

Also, winter tyres won't be so good in summer eh.

Haha ..

Actually these tyres are very soft and traction is horrible if not scary!

Makes for a good show though

That's why I need to change them but they're okay for getting an idea about sizes / clearance

(since the whole debate)
